Failure Analysis of Composite Laminates Using a Tensor Polynomial Strength Criterion,

Abstract

This report presents a summary of the work done on the development of the cubic form of the tensor polynomial strength criterion for composite laminates. The capability of this model to accurately predict multi-mode failures for a range of laminates under various load conditions is demonstrated, and the results compared to quadratic model predictions. Both symmetric and nonsymmetric laminates have been considered. Furthermore, the effect of nonlinear shear stress/strain behavior is included to provide some insight as to its role in determining the strength of laminates. Of particular interest is the application of this criterion to the strength analysis of laminates containing circular holes. (Author)
